Abstract (en)
[origin: US2014305240A1] A handbrake for a railroad car includes a handbrake body having one or more gear train components therein and a drive shaft operatively connected to the one or more gear train components. An intermediate pinion shaft is operatively connected to the drive shaft through one or more gears. A shaft alignment link is adapted for maintaining a relative spacing between the drive shaft and the intermediate pinion shaft during rotation of the drive shaft. A gear box housing is provided to enclose at least a portion of the drive shaft, the intermediate pinion shaft, and the shaft alignment link. The shaft alignment link is movable relative to the gear box housing due to any eccentric movement of the drive shaft to maintain the proper spacing between the drive shaft and the intermediate pinion shaft, thereby eliminating a possibility of gear binding. A method for aligning internal gear components within a handbrake and an alignment system for use with a railway vehicle handbrake is also provided.
